After betraying the Potters, Pettigrew was pursued by Sirius Black, and was eventually cornered by him on a crowded London[1] street. Pettigrew then loudly accused Black of betraying the Potters, created an explosion, and escaped, leaving behind a finger he had cut off to fake his death. This explosion claimed the lives of twelve Muggles and left a deep crater in the street. Surviving Muggle witnesses reported what Pettigrew said to Ministry of Magic officials. Thus framed, Black was imprisoned in Azkaban without trial.

The Ministry of Magic had difficulty covering up this event given the extent of the damage and the number of Muggle casualties.[4] They erased the memories of surviving Muggle witnesses[3] and disseminated the story that the explosion had been caused by a leak in a gas main.[4]
